Took the cylindrical roller bearing in wind turbine as research obj ects,the finite element method was used for its static and dynamic characteristics.Considering the different load,different number of rollers and hollow degree change on the stress distribution and deformation,multi-bodies contact for rolling bearing and finite element model were estab-lished.Finally,the finite element modal analysis of rolling bearing was studied.The methods and conclusions of this study provided scientific proof and basic data for further study of the design and manufacture of rolling bearing in wind turbine and related contact problems.
